Unit 05: Force, Motion & Energy Practice

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

Which object has kinetic energy?

Back

A moving skateboard has kinetic energy.

Front

What happens to an object's motion when a greater force is applied?

Back

The object will accelerate.

Front

What can change during a collision?

Back

The motion of the objects involved can change.

Front

What does it mean when a car is moving north at 60 km/h?

Back

It describes the car's direction and speed.

Front

Define force in the context of motion.

Back

Force is a push or pull that can cause an object to accelerate.

Front

What is the relationship between force and acceleration?

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

How does mass affect kinetic energy?

Back

Kinetic energy increases with the mass of the object, as it is calculated using the formula KE = 1/2 mv².

Front

What is the formula for calculating kinetic energy?

Back

The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.
